Description

Technical Field

[0001] The invention relates to panel glass drying, and in particular to panel glass drying equipment. Background Art

[0002] Flat Panel Display refers to a panel that is manufactured in a flat shape to display images, such as LCD, PDP, OLED, FED, etc. With the rapid development of the information age, the demand for such flat panel display panels has increased exponentially. They are manufactured by forming components on panels such as glass substrates through various steps on an automatic production line.

[0003] In the manufacturing process of panel glass, a step of cleaning the substrate must be performed during various steps. In addition, after the cleaning step is completed, a drying step is required to completely dry and remove the deionized water used in the cleaning.

[0004] In the past, in the process of drying such panel glass, a flat panel display panel drying device such as an air knife was often used to spray high-temperature and high-pressure compressed air directly onto the surface of the flat panel display panel to quickly remove moisture. However, the existing air knife drying method has the problem of easily generating water residue on the glass surface, resulting in poor process.

[0005] Therefore, drying devices have recently been developed to reduce the possibility of water residue on the glass surface, including hot air heaters, lamp heaters and infrared heaters. However, the above-mentioned drying devices will generate particles, which will affect the quality of the panel glass surface and need to be replaced regularly, which increases the cost. In addition, the above-mentioned drying devices need to adjust the distance between the drying device and the panel glass through structures such as several cylinders or hydraulic rods to improve the heating efficiency.

[0006] However, the above drying structure has the problems of unstable lifting transmission and unsteady movement during the movement, and cannot dry the entire area of ​​the panel glass and cannot cope with various types of panel glass. Summary of the invention

[0008] To achieve the above purpose, the roller transmission component is used to facilitate the transmission of the panel glass, the mica heater A is used to dry the panel glass, and the mica heater can achieve the effect of completely drying the moisture on the glass surface. The power cylinder is used to drive the mica heater A to move in the vertical direction, and the mica heater A is close to the panel glass to improve the drying efficiency of the panel glass. The movement of the mica heater A will drive the rack fixedly connected to the mica heater A to move. The guide component guides the movement of the four racks, realizes the synchronous lifting and lowering of the four racks, realizes precise and stable lifting movement, can dry the entire area of ​​the panel glass, and can cope with various types of panel glass.

[0009] Furthermore, the guide assembly includes two horizontally arranged A connecting shafts, each of the A connecting shafts is located between two adjacent racks, both ends of the A connecting shafts are connected to the adjacent racks through an L-type gear box, and a B connecting shaft is provided between the two A connecting shafts, and both ends of the B connecting shafts are connected to the adjacent A connecting shafts through a T-type gear box.

[0012] Through the above technical solution, the movement of mica heater A will drive the movement of the rack fixedly connected to mica heater A in the vertical direction. Through the action of the L-type gear box, the movement of the rack will drive the rotation of connecting shaft A. Through the action of the T-type gear box, the rotation of connecting shaft A will drive the rotation of connecting shaft B. Through the coordination of the rack, L-type gear box, connecting shaft A, connecting shaft B and T-type gear box, the movement of the four racks is guided, and the synchronous lifting and lowering of the four racks is realized, and precise and stable lifting and lowering movement is realized.

[0013] Furthermore, a guide column is fixedly provided on the skeleton and is located directly below the rack. The guide column is a tubular structure with an open top and a hollow interior. The end of the rack away from the mounting plate passes through an L-shaped gear box and enters the guide column. The rack is slidably connected to the guide column, and the guide column is fixedly connected to the L-shaped gear box.

[0014] Through the above technical solution, the guide column plays a guiding and supporting role in the movement of the rack.

[0015] Furthermore, an axial connecting plate is fixedly provided at the bottom end of the skeleton, a groove is provided on the side of the connecting plate facing away from the A mica heater, a drag chain body fixedly connected to the electrical wire of the A mica heater is movably connected in the groove, and a dust suction component is provided on the side of the drag chain body facing away from the connecting plate to reduce dust generated by friction between the electrical wire and the drag chain body during movement.

[0023] Furthermore, the air curtain assembly includes a strip square tube fixedly connected to the outer wall of the frame. The strip square tube is a tubular structure with one end closed and the other end open, and the interior is hollow. The strip square tube is provided with a plurality of through holes on the side facing the panel glass for supplying air to the panel glass.

[0024] Through the above technical solution, the device adopts any existing method for inflation operation in the prior art, such as an air pump, so that air enters the strip square tube through the open end of the strip square tube and then flows out through the through hole.
